IMPROVEMENT IN HEATERS AND FEEDERS FORBOILERS.

Specification forming part of Letters Patent No. 144,937, dated November 26, 1873; application filed January 25, 1873.

sectional elevation of the apparatus I use for inducing the circulation.

c A is the boiler, which may be of any kind. B B is the fe'edwater pipe, into which the pipes D D' enter at C and C', the pipe D being connected with the boiler at E, or at any point where the water may be supposed to be most quiet, and pipe D being connected to the boiler at I. The waterforced along the feed-pipe B B past the junctions with pipes D D', naturally induces currents from the boiler at E 'and I by the friction of its particles with the particles of the water coming in at the other pipes, which, uniting with the feed-water, re-enters theY boiler again along with it at F. To increase this action\ I prefer to arrange a contrivance similar to the head of a steam siphon or injector at G`; also, another at G', if

I prefer, by which I can cause the passage of a volume through D' several times larger than the volume of the feed-water in B 5 also, a volume in D as much larger than the volume in B', but this is not absolutely necessary, for, by enlarging the feed-pipe above the junction ofthe circulating-pipes, very good results may be obtained 'without the Siphon-head. I prefer to have the feed-pipe and the pipe D extend into the boiler to some extent beyond the shell, as snown at H, as a further means of promoting the circulation 5 but this is not es# sential.

By this plan the water will constantly flow through the boiler and' pipes, and a good circulation will be maintained; and, besides, the feed-water will be heated nearly to the -degree of the water in the boiler, whichis much greater than it can be heated by the ordinary feed-wa ter heaters; and thus the boiler will be relieved to a greater extent than usual of the effects of the cold water on the hot surfaces.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with boiler-piping H E D E H, of the injection G' and G', feed-pipe B inserted at C, and'having its end projecting above that of boiler-pipe D and pipe D', as and for the purpose described.
